As a GrapheneOS user, I've had to buy pixel watch 2 in order to be able to pay via Google Pay abroad (since I unfortunately happen to reside in an internationally sanctioned country, local cards work only inside the country, some crypto exchanges provide Visa/Mastercard cards, but virtual only, so Google/Apple pay is the only choice). I really wish I haven't had to own this android-certified™ device in the first place. Have had to disable as much GMS system permissions as possible, such as pulse, GPS, physical activity via ADB.
P. S. Since it's not even possible to add a new card if the watch is paired to a device that doesn't pass SafetyNet, I've had to add cards with a stock android device, and then re-pair the watch to GrapheneOS device. This almost seems like a deliberate choice by Google.
To de-Google, I have
GrapheneOS + a Garmin Instinct 3 Solar:
- 28 day battery life
- NFC payments that work internationally
- always-on monochrome MIP display that is very readable in direct sunlight
- sleep tracking with silent alarms
- phone ring alerts
- very good GPS for outdoor activities
Best of all, since you only need to charge it once a month, the watch will last 10+ years.
I've considered Garmin for Garmin pay, but seems like it supports much less banks, and I didn't want to gamble with checking for myself if it'd work with virtual crypto cards. Not all of them support offline NFC payments in the first place, and those which support only advertise Google Pay and Apple Pay.
Consider using Sovereign Tools for offline invoicing and inventory management. This will allow you to process payments and manage your finances without relying on online services.
